Call Paul or Adrian at Schumacher USA. They'll get you taken care of.

I finally beat you to a reply....LMAO

Fianlly beat me at something

the car simply died out... couple of secs later it came back to life could it be the sign of rapida overheating and automatically switched itself off? i'm by the equator where at noon track temp can easily go pass 50C

excuse me for being dumb but what does 50C come out to in F? I've run mine at track temps of 150F without any problems. Not to say that yours should work in those temps. Have you played with the features of the speedo and gone to the temp setting to see what the speedo is operating at? That may give you an idea as to what the problem may be. When the shut down happens do you still have steering power? Let's check it all out so that you never have a DNF in any of your races.

50C = 122F. The initial setting (which i didn't have driving problem) was close to default P5 values except for drive & brake freq which were 4KHz, neutral brake freq was 5KHz and motor brake was 2%.

i felt motor braking was giving me some turning problem, so i turned it off and increased drive and brake freq both to 5KHz. this is when the problem started. all the time, ensa was at 100% with no diode on the motor.

i missed the temp. reading since this is my 1st outing with rapida.

150F track temp that's 65.5C ... about as hot as the 2nd leg of F1 which was said to be the hottest leg in F1 this year we also got high humidity to tackle

...forgot to mention... when the car died down, it was so abrupt with zero steering

I've run on track temps in Southern California over 150F. But I've not have a problam with the ESC's shutting off. Did you still have steering or no power at all?

Oops, that answered my question. You beat me to it. I don't know if the ESC has an actual thermal shut down. I'll look into it for you.

I have run it many times and when I fiinish a qualigying or final the reading wais 52C with no problem at all.

I have noticed that my car doesn't brake as much as it used to. Imagine that I was going full throttle and hit the brakes wihtout spinning around as I should considering I'm using a one-way and the settings is at highest!! On the esc it;s the P5.
Any ideas?

I've noticed the same deal, doesn't brake as much as it use to before I had the Keyence and I'm on the 'P5 setting too - JB

yet the nice guy that I am here's your answer (I hope).

Even running in 540 stock I have noticed a similar thing (when I'm using ensa at 100%).

Sure it puts power back into the battery and saves from having to us a diode but I certainly notice a difference when I turn ensa off and use a diode. Let's just say the braking is obviously stronger.

I'm assuming that with ensa the electricity flowing back to top up the battery is removing the *like chucking it into reverse "feeling"* of the brakes which feel quite brutal with a diode.

I don't know what the technical explanation is but I always saw the diode as preventing the "flow back" so to speak but as such with no place to go back to the shorting/braking effect is greater on the motor.

So basically what I've found is that with a diode 20% is enough but without a diode I've had to increase to 40% (just short of the "typical" setting for 540 stock).

Just a thought.

Ps: I see the P5 setting is only 10% minimum brakes.

I tried that when I first got mine, well sure it stops but in 540 stock you might as well not have any brakes if you want to stop in a hurry.

I suggest that rather than use the pre sets P4,5,6 or 7 use the "typical" settings, in stock and mod it's 15% as the starting point for braking.

You actually have to hit the brakes with a Mabuchi? Sorry, Just Kidding. I had to say it though. It was wide open.

even on a otherwise wide open track you sometimes find things called hairpins.

Unfortunately I've lost count of the number of times that I've braked to avoid a mishap but the person behind me doesn't or doesn't care and just goes for it.

We need brake lights. lol

I'm glad you took that as a joke. After I posted it I was worried you might get offended.
